6 Claims.

This invention relates to an improved sterilizing hood for use inconnection with a centrifugal cream separator, and. one object of theinvention is to provide a sterilizing hood so constructed that the bodyportion thereof may be formed from a hood such as is ordinarily used inconnection with a centrifugal separator.

Another object of the invention is toso construct, this sterilizing hoodthat the ordinary hood of a centrifugal separator'may be converted intothe improved construction by adding partitions which will divide the.usualv cream and milk compartments of the hood and thus provide milk andcream compartments which are enclosed in compartments receiving thesteam.

Another object of the invention is to so construct this sterilizinghoodthat the reservoir into which the milk "will be poured may be carried bya cap fitting upon the body portion of the hood, the reservoirbeingprovided with a centrally located depending outlet pipe which willextenddownintothe centrifugal separator. This invention is illustratedin the accompanying drawings, in which.

Figure 1 is a view showing the improved sterilizing hood in verticalsection, the centrifugal separator being indicated in dotted lines,Figure 2 is avertical sectional view through the sterilizing hood takenat right angles to the disclosure in Figure 1,

Figure 3 is a transverse sectional view taken along the line 3-3 ofFigure 1, and

7 Figured is a vertical sectional view through a set of partitionsforming the invention.

This improved sterilizing hood is used in connection with a centrifugalseparator which is indicated'by dotted lines inFigur'e 1' and designatedby the numeral133 A hood which is of a conventional construction isprovided'about the upper portion of the separator drum 33 as shown inFigure land will be provided with the improvements forming thesubject-matter of this invention so that this hood will be convertedfrom a hood of a conventional construction to the improved sterilizinghood.

This hood is provided with a lower section 9, and an upper section Ii!which fits into the lower section is provided with an outstanding bead'Gwhich engages the upper edge of the lower section so that the uppersection will be supported upon the lower section. The lower section isprovided with an inwardly extending flange 8 which carries a dependingneck 1 and further carries which the separator drum 33 extends. Theupper section I is also provided with a substantially frusto-conicallower wall II which extends.

upwardly into the upper section and is provided with a centrally locatedopening 13 positioned in alignment with the opening 14 of the wall l2 sothat the upper end of the separator drum may extend through this wall Il into the upper section I0 of the hood. It will thus be seen that thehood will be placed about the upper end portion of the separator drum 33in the usual manner and the separated milk and cream will pass from theseparator drum into the upper and lower sections of the hood.

In order to convert the hood into a sterilizing hood, the upper sectionwill be provided with frusto-conical partitions 20, 2| and 22, and thelower section will beprovlded with frusto-conioal partitions 23, 24 and25. From an inspection of Figures 1 and 2 it will be readily seen thatthe .partitions 20 and 23 form upper walls for the upper and lowersections of the hood and that these partitions 0r walls will 'besoldered or otherwise rigidly connected with the side walls of the upperand lower sections of the hood. The partition 2| has its upper centralportion soldered or otherwise rigidly connected with the partition 20,and this partition terminates in spaced relation to the side walls ofthe upper section and is rigidly connected with the outer edge portionof the partition 22. This partition 22 fits about the lower wall II andis rigidly connected with this lower wall. It will be thus seen that thepartitions 2| and 22 serve to divide the space between the partition orwall 2 0- and wall H into inner and outer compartments 2' and 3, the inner compartment '2 being the cream compartan upwardly extendingfrusto-conical wall I2 having a centrally located opening l4 throughment and the outer compartment 3 a steam compartment. I

In order to similarly divide the lower section of the hoodinto a milkcompartment 4 and steam compartment 5 there has been providedfrustoconical partitions 23, 24, and 25. This partition 23 is solderedor otherwise rigidly connected with the side walls of the lower section9 and is connected with the upper central portion of the partition 24about the central opening formed therein. This'partition2'4 is solderedor otherwise rigidly connected with the side walls of the lower section9 and is connected with the upper central portion of the partition 24about the central opening formed therein. This partition 24 has itsouter end I4 terminating in spaced relation to the side walls of thelower section 9 and is rigidly connected with the outer edge portion ofthe partition 25. This partition 25 fits about and is rigidly connectedwith the lower wall I2 of the lower section.

The upper section of this sterilizing hood carries a cap or head 30 uponwhich is mounted the reservoir 3| into Which the milk to be separatedwill be poured, and this reservoir is provided with a centrally locateddepending outlet pipe 32 which extends down into the upper end of thecentrifugal separator drum 33 when the hood is in place, as shown inFigure 1. The cream will be separate from the milk in this drum in theusual manner and the cream will pass out of the drum into the creamchamber 2, the skimmed milk passing from the drum into the milk chamber4. Steam is admittedt-o the steam chambers 3 and 5 through branch pipes.

, I! and I8 which lead from the steam pip I9 through openings I5 and I6formed in the side walls of the upper and lower sections 9 and ID of thesterilizing hood. This steam will heat the cream and milk in thechambers 2 and 4, and the cream andmilk will thus be thoroughlysterilized as they pass through the sterilizing hood, The milk and creampass from the chambers 2 and 4 through outlet pipe 26 and 21 which.extend through the upper and lower sections of the sterilizing drum and.fit into openings 28 and 29 formed in partitions 2| and 24.

These pipes may be led through a compartu ment 34 containing ice wateror some other cooling medium so that the heated milk and cream may becooled.

When in use, this sterilizing hood is placed over the upper end portionof the separator drum 33 and the milk is poured into th reservoir 3|from which it passes into the drum through the pipe 32. The cream andskimmed milk will pass from the drum into the compartments or chambers 2and 4 where they will be sterilized by the heat from the steam in thechambers 3 and 5, and the milk and cream will then pass out of thechambers 2 and 4 through the outlet pipes 26 and 21. When it is desiredto clean this sterilizing hood the head or cap 30 will be removed fromthe upper section of the hood and th upper section removed from thelower section. The two sections of the hood and the head can then beeasily and thoroughly cleaned and the hood re-assembled. There has thusbeen provided a sterilizing hood which is so constructed that the bodyportion thereof will have a construction similar to that of aconventional hood for a centrifugal separator. There has further beenprovided ,a sterilizing hood which is simplein construction andefiicient in operation.
